Dear MF, I was well aware that the link I gave was the 'first level' link to family reunification and I gave it deliberately rather than the 'sub-link' you chose.
I suppose I'm a great believer in 'give a guy a fish and he has a meal, give him a fishing rod and he can learn to feed himself' or whatever the correct quote is.
Mostly folk can find their way around Sites better 'from the general to the detail' as they see what other areas are covered. Giving the exact link which contains the information they require at this moment, means that they often don't see (or bother to look at!) all the wealth of information which is available if they were to go 'backwards' through the site.
To my mind, www.ch.ch
(Eine Dienstleistung des Bundes, der Kantone und Gemeinden) should be compulsory reading for everyone who wants to ask questions on here.
